Re: Wgrywanie firmware przez TFTP Tutorial - proline - 12-08-2015

Hi.
I have problem with LK 2.0
Firmware upgrade by TFTP from 3.07 to 3.13 was fail on 41%.
Now I have 2pcs LK 2.0 with same problem - blink green led in LAN port (without cable connection) and LK no access via LAN when cable connected.
Reset and repeated upgrade firmware didn't work.
What can i do?

Hello,
I also have a similar problem. I have a LAN controller ver.2.00. My friend gave it to me after it screwed as he didn't want to play with it. LK control is in boot mode. The green LED flashes for about 8-10 seconds and then pause for about 20 seconds. I read that this is okay because it is a V2 controller. It does the same with and without LAN cable. In my opinion it does not respond to the RESET button.
I tried to do the tftp-i upload on three computers but it did not work. I tried to do as described in the documentation (page 25) but did not succeed.
What do I do wrong? Please help me!
Can I do something with external programmer?

Thanks in advance!
Zoltan

I think there is no corresponding IP address, it is also the problem.
Here in the forum I read, that using the boot mode, the microcontroller reads of the EEPROM the IP address. This is IP address 192.168.1.100.
I tried this IP address. Did not work, unfortunately.

Thanks for your help!

The IP address is 192.168.1.100, if there was a previously set, but maybe it was set to another, and you don't now it.
You may scan (change ip) interfeces network( with LK) on port tftp (69) and observe in wireshark if LK responde by ethernet frame.
Or if you have eeprom programer, write from address 2, four byte with IP value. When you write eeprom you must keep with reset MCU.
